Observe the demonstration plate of a catalase-negative Gram positive coccus.  This is a positive A test. The A disc contains bacitracin, and the P disc contains optochin.  Based on the observable test, the most likely genus and species of this organism is:

Design an oral rehydration therapy (ORT) formula that includes appropriate solutes, such as Na⁺, Cl⁻, glucose, and any other relevant components. Specify the concentrations of each component and justify your design choices. In your discussion, explain how your formulation achieves electrolyte balance, promotes appropriate osmotic effects, and maximizes absorption efficiency. Finally, explain how solubility, electrolyte behavior, and colligative properties work together to determine whether a solution is safe and effective for medical use.

Explain the differences between colloids and true solutions. Then discuss why colloids are generally not absorbed efficiently across biological membranes, whereas true solutions are better suited for rapid transport and rehydration. In your explanation, connect particle size and solute behavior to membrane transport.

A drug is introduced that alters blood pH. Predict how this change would affect enzyme function, oxygen binding by hemoglobin, and chemical equilibrium within the body. Then explain how changes at the molecular level—including bonding, concentration, energy transfer, and gas behavior—can lead to large-scale physiological effects in human systems.
